    I am currently beta testing a ZTE smartphone, and it is currently running on Straight Talk Verizon network. The phone will only connect to 3G, even in areas with Verizon 4G LTE coverage. The only way to enable 4G is through the testing menu at *#*#4636#*#*, and select LTE only. However, in this mode, I cannot make calls. I also know that it is not an issue with the other devices, as no other tester is having these issues. I also confirmed with Straight Talk that it is not their network. I have tried everything, from reboots to sim pulls, to hard resets. Anyone have any suggestions for me?
